The cast for The Walking Dead continues to grow in the wake of last season's spring cleaning.

The series has added Alanna Masterson to the cast, reports Deadline. Masterson's character will recur in the upcoming fourth season "with an option to become a regular in Season 5 of the zombie drama."

While her specific role hasn't been revealed, it's been rumored that she'll play Tara Chalmers, a character from the Rise of the Governor prequel novel. Masterson is the sister of That 70's Show alum Danny Masterson, and she marks the second new addition to the cast in as many weeks, following the role given to a Twilight alum...
